Premium app cover poster, 1:1 square composition, clean and uncluttered, flat front view with no perspective distortion. Huge bold title text "GPT-5.6 TERRA PRO" laid out FLAT and HORIZONTAL across the TOP of the frame, facing the viewer straight on, never tilted or in perspective, in modern geometric sans-serif, glossy chrome with a vivid colour gradient, razor-sharp edges, perfectly legible, spanning about 85 percent of the width, with a soft neon glow and drop shadow. Directly beneath it one thin clean subtitle line "OPENAI - 1M - REASONING" in crisp minimalist uppercase letters, perfectly readable. Filling the lower two thirds: a glowing topographic globe of thin emerald contour lines rotating in dark space, subtle grid, premium sci-fi look. Cinematic colour grading, hyper-detailed, sharp focus on the text, flagship poster quality, no extra words or labels.
